Read the safety rules for metalwork
Discuss how to be safe while working with metal.
Discuss with your counselor the additional safety rules that apply to the metalwork option you choose for requirement 5.

Define the terms native metal, malleable, metallurgy, alloy, nonferrous, and ferrous. Then do the following:

Name two nonferrous alloys used by pre-Iron Age metalworkers. Name the metals that are combined to form these alloys.

Name three ferrous
alloys used by modern metalworkers.

Describe how to work–harden a metal.

Describe how to anneal a non-ferrous and a ferrous
metal.

Do the following:

Work-harden a piece of 26- or 28-gauge sheet brass or sheet copper. Put a 45-degree bend in the metal, then heavily peen the area along the bend line to work-harden it. Note the amount of effort that
is required to overcome the yield point in this unworked piece
of metal.

Soften the work hardened piece from requirement 3a by annealing it
and then try to remove the 45–degree bend. Note the amount of
effort that is required to overcome the yield point.

Make a temper color index from a flat piece of steel. Using hand tools, make and temper a center punch of medium-carbon or high-carbon steel.

Find out about three career opportunities in metalworking. Pick one and find out the education, training, and experience required for this profession. Discuss this with your counselor, and explain why this profession might interest you.

After completing the first four requirements, complete at least
ONE of the options listed below.

Option 1 – Sheet Metal Mechanic / Tinsmith

Name and describe the use of the basic sheet metalworking
tools.

Create a sketch of two
objects to make from sheet metal. Include each component's
dimensions on your sketch, which need not be to scale.

Make two objects out of 24- or 26–gauge sheet metal. Use patterns
either provided by your counselor or
made by you and approved by your counselor. Construct these objects using a metal that is appropriate to the object's ultimate purpose, and using cutting, bending, edging, and either soldering or brazing.

One object also must include at least one riveted component

If you do not make your objects from zinc-plated
sheet steel or tin-plated sheet steel, preserve your
work from oxidation.

Option 2 - Silversmith

Name and describe the use of a silversmith's basic tools.

Create a sketch of two
objects to make from sheet silver. Include each
component's dimensions on your sketch, which need not be to scale.

Make two objects out of 8- or 20- gauge sheet copper. Use
patterns
either provided by your counselor or
made by you and approved by your
counselor. Both objects must include a soldered joint. If you have prior silversmithing
experience, you may substitute sterling silver, nickel silver,
or lead free pewter.

At least one object must include a sawed component
you have made yourself.

At least one object must include a sunken part you
have made yourself.

Clean and polish your objects.

Option 3 – Founder

Name and describe the use of the basic parts of a two–piece
mold. Name at least three different types of molds.

Create a sketch of two
objects to cast in metal. Include each component's
dimensions on your sketch, which need not be to scale.

Make two molds, one using a
pattern provided by your counselor and another
you have made yourself that has been approved by your
counselor. Position the pouring gate and vents yourself. Do not use copyrighted
materials as patterns.

Using lead-free pewter, make a casting using a mold provided by your counselor.

Using lead-free pewter, make a casting using the mold
that you have made.

Option 4 - Blacksmith

Name and describe the use of a blacksmith's basic tools.

Make a sketch of two
objects
to hot-forge. Include each component’s dimensions on your
sketch, which need not be to scale.

Using low–carbon steel at least ¼ inch thick, perform
the following exercises:

Draw out by forging a taper.

Use the horn of the anvil by forging a U-shaped
bend.

Form a decorative twist in a piece
of square steel.

Use the edge of the anvil to bend metal by forging
an L–shaped bend.

Using low-carbon steel at least ¼ inch thick, make
the two objects you sketched that require hot-forging. Be sure you have your counselor's approval before you begin.
